' Application filed March 10,1917. .Serial No. 153,995.

To all whom it may concern Be it known that I, ALBERT T. FAY, a c1t1- Zen of the United States, residing at Minna apolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Wheat-Heaters, of which thefollowing is a specification.

My invention relates to wheat heaters, and has for its object to provide a, wheat heater of the type which employs a substantially horizontal rotating cylinder with a closure at the grain admission end of said cylinder such as to form a permanent seal to permit any leakage of grain back throughthe joints between the stationary and'moving parts at.

said receiving end.

The full ob ects and advantages-of my invention Wlll appear 1n connectlon with the detailed description thereof, and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention in one form,-

Figure 1 is a transverse sectional view of looking through the same toward the receiving end thereof. Fig. 2 is a fragmen-.

tary side elevation sectional view through sectional detail much enlarged.

As illustrated, a cylinder 10 is supported in rotating relation by rollers 11 which engage metal bands 12 on the cylinder, said rollers 11 being journaled upon end frame castings of which the casting 13, at the grain receiving end of the wheat heater, is shown. This casting is provided with legs 14 and 15 and acentral body portion 16. This body portion 16 is provided with an inwardly ex-- tending cylindrical drum member 17 through which extends obliquely a grain delivery spout or chute 18. The interiorof cylinder 10 is provided with blades 19 which, receiving the grain, as the cylinder rotates, lifts the grain to the upper portion of the cylinder and pours it down through a battery of heated pipes, repeated contact with which heats the grain to the desired temperature. A few only of the heated pipes 20 are shown which extend through the inner wall 21 of the drum 17 and are thereby supported and in turn support'the battery of pipes in a well known manner.

The end of rotary drum 10 is partly closed by. an annular plate 22 having acentral circular opening 23 which is in the plane of the 25 which fits tightly around drum 17; The ring 25 is driven upon drum 17 so as to bring bers 27 and 28 whichmembers overlap and inner wall 21 of the drum 17 andis spaced a suitable distance. therefrom. An annular flange or jlip piece 24 is rigidly secured by rivets 30 or other suitable means to a ring the lip 2 f exactly into the plane of plate 22 and: the ring is preferably held in nonturn-. ing relation to drum 17 by a key or keys 31. i As before stated, the plate 22 and the lip 24lare in the same plane, and the circular edges thereof approach quite close to one another but are spaced a sufficient amount, as. indicated at 26, to permit a requisite amount of relative approaching and receding movement, as the movable plate 22 rotates with cylinder 10 about the immovable flange 24:. Secured to plate 22 adjacent the circular edge-23 thereof, are a pair of annular mem-.

straddle the lip 24, andare held in. close engagement therewith; as they rotate with plate 22 and cylinder 10. a wheat heater embodying my invention,

'The advantages of'my invention will be obvious. The drum-face 21, annular lip 24, and annular plate 22 form a plane-faced clo- 1 sure to the receiving end'of cylinder 10 in which the portion 2124 is stationary, and the portion 22 is rotary. A space between them 26, suflicient to permit all necessary relative movements, istightly sealed against escape of grain by the annular pieces 27-28 which straddle the lip 2 1 and are secured to move with the plate 22. It follows that all grain which enters the cylinder through the chute 18, and which is thereafter violently agitated and thrown around and 'about in the cylinder by the blades 19, must remainin the cylinder as the joint between the moving portion and the stationary portion of the tightly sealed. 7

I claim: v 1. A wheat heater comprising an end support and a substantially horizontal cylinder 10'0 inder adjacent said end support comprising 105 a member rotating with the cylinder and a member held stationary upon the end support, and means continuously sealing, in

grain tight relation, the adjoining portions of said movable and stationary members.

end wall of the cylinder is, at all times,

2. A Wheat heater comprisingan end support and a substantially horizontal cylinder rotatablysupported at one end thereby, sa d end support being provided with a grain ad- I mission spout extending through the same, means closing the end Wall of the cylinder ad acent said end support COIHPIlSlHg a member rotating with the cylinder and a member held stationary upon the end sup joining portions of the movable and station 'ai'y members. 7

3. A Wheat heater comprising an end support and a substantially horizontal cylinder rotatably supported at one end thereby, said end support including a closed inwardly extending drum having a grain admission chute extending obliquely through the same, an end Wall for the cylinder comprising a member secured thereto and movable there with. and a stationary member secured to the drum in the plane of the movable men1- her, and means continuously sealing in grain tight relation the adjoining portions of said 'IIJOVZibl and stationary members.

a. A Wheat heater comprising an end support and a substantially horizontal cylinder rotatably supported at one end thereby, said end supportincluding a closed lnwardly extending drum hav ng 7 a grain admisslon chute extending obliquely through the same,"

an .end Wall for the cylinder comprising an annular plate secured to the cylinder and movable) therewith, and an annular plate fast With the drum and extending in the plane of the first named plate, and a pair of .annular members secured to the rotating plate and straddling the stationary plate for continuously sealing in grain tight relation the adjoining edges of said rotating and sta tionary plates. V

5. A wheat heater comprising an end sup port and a substantially horizontal cylinder rotatably supported at one end thereby, said end support including a closed inwardly extending drum having a grain admission chute extending obliquelythrough the same, an end Wall for the'cylinder comprising the inner end Wall of the drum, an annular plate secured to the drum in the plane of said ALBERT 'r. FAY.
